Definitions
- the proposed invention relates to the field of cutting elastic, mostly web-like material.
- Such devices often have a guide which is mounted transversely to the running direction of the web-like material in a machine frame or the like, to which a knife can be attached, which is able to cut the web-like material in its running direction.
- a clamping device is often used to fasten the respective knife in a desired position along the said guide, so that a carriage, slide or the like, which can be moved along the guide, is inserted and fixed on this guide can.
- carriages or the like are often equipped with a switchable coupling device, by means of which a mechanical coupling can take place between the carriage or the like and at least one of the knives in order to move the respective knife into a previously desired position.
- Such a device is already known, for example, on the basis of German Patent 30 47 976.
- the device described here uses knives which are able to work with a counter knife in each case in order to cut a web-like material into narrower strips.
- it is known, for example from German patent specification 10 24 341, to store a so-called upper knife in a corresponding device in such a way that it is optionally able to cooperate with one of several edges of a sleeve-like counter or lower knife.
- Fig. 1 side view
- Fig. 2 field of view
- Fig. 3 side view, partially cut
- An elastic web-like material 1 coming from the cutting device 3 comes in the direction of the arrow 2.
- the material 1 wraps around the guide rollers 4 and 5 and the lower knife 6, for example.
- several such lower knives can be arranged one behind the other.
- Each lower knife 6 has at least one cutting edge 7, but preferably a plurality of cutting edges, for example the further cutting edges 8 and 9.
- At least one upper knife 10 works together with each lower knife, preferably in such a way that each upper knife 10 is optionally with one of the cutting edges 7 to 9 or the other cutting edges can work together.
- a plurality of analog upper knives 10 can also be arranged one behind the other.
- Each upper knife 10 is rotatably mounted on a carriage 12 with the aid of at least one bearing block 11. If desired, the upper knife 10 can also be driven, for which purpose a corresponding motor can be expediently fastened on the carriage 12, for example.
- 1, several carriages 12 can be arranged one behind the other.
- Each carriage 12 is displaceable along a guide 13 which is fastened in the machine frame 14 in such a way that the respective carriage 12 can be displaced across its width at right angles to the direction of travel of the material 1 indicated by the arrow 2.
- Another guide 15 is provided on the machine frame 14 parallel to the guide 13.
- This guide runs parallel to the guide 13 and carries a carriage 16, which is also parallel to the guide 13 and thus parallel the respective carriage 12 can be moved.
- a motor 17 is fastened, which can drive a gearwheel 18, which in turn can engage a rack 19.
- the rack 19 is also fastened parallel to the guide 13 in the machine frame 14.
- the carriage 16 can be moved along the guide 13 or parallel to it by starting the motor 17, which is equivalent to the fact that the carriage 16 is able to move itself transversely to the direction of travel of the material 1.
- a pressure medium cylinder 20 or the like, to which a piston rod 21 belongs, is also fastened on the slide 16. When pressure medium is introduced into the pressure medium cylinder 20, the piston rod 21 can be shifted to the right in FIG. 1, so that it is able to move into a
- a CCD camera 23 is also attached to the carriage 16 in such a way that it is able to cut the so-called cutting point 24 to observe.
- the CCD camera is, for example, such a camera which scans its field of vision line by line and is able to distribute each line into individual areas, such as such a camera from Honeywell, criz-Systeme GmbH, Kaiserleystrasse 39, Offenbach am Main,
- Position is shifted to reorient or correct using the auxiliary scale 25.
- the CCD camera can give a correction command to the motor 17 via a corresponding control device in such a way that it is guaranteed in each case that the respective upper knife 10 can enter the so-called cutting groove 27 assigned to the cutting edge 7 without the upper knife 10 or its cutting edge could hit the cutting blade 7, for example its cutting edge 7.
- the distances 28 and 29 remain greater than zero in any case, so that the upper knife 10 can certainly dip into the cutting groove 27.
- the widths 30, 31 etc. of the cutting grooves 27 can be made slightly different from one another, so that the CCD camera can register when scanning the cutting grooves how wide the cutting groove just opposite it is. In this way, the result of their scanning can be compared with the result reported by the counter 26.
- the exact position of the edges of the cutting grooves 27 is known in each case, it is possible to correct the counter 26 or its zero position if necessary. This is advantageous, for example, if the rack 19, for example wise should have become slightly inaccurate due to thermal expansion during operation of the facility.
- material 1 is not shown in FIG. 2.
- the knife that is usually available alone or at relatively large intervals is referred to as the so-called upper knife
- the counter knife that works with the upper knife, regardless of whether it contains only one or more usable cutting edges is usually referred to as the lower knife.
- This designation also applies if - as in the present case - the so-called lower knife in the figures above and the so-called upper knife in the figures below should be arranged over the width of the material 1, for example only one carriage 16 can be present , which can be coupled with at least one, but preferably a plurality of slides 12 as required.
- the slides 12 and 16 can also be designed as carriages with rollers or the like in order to meet the requirements described.
- the piston rod 21, together with the coupling 22, represents a coupling device.
- a plurality of slides or the like 16 can also be displaceably provided on the guide 15, which can each be used for optionally coupling into a plurality of slides or the like 12.
- the proposed device is particularly advantageous when it is not only a matter of first removing the respective upper knife in front of its associated lower knife and then approaching it again. Rather, it is particularly advantageous if the upper knife is first removed from its lower knife, then moved along the guide 13 in order to then be approximated to another lower knife, if a so-called format change is carried out.
- the proposed facility is not just for that
- Suitable for cutting with circular knives but also when at least one flat so-called razor blade knife is to interact with the grooves of a corresponding rotating circular lower knife.
- a CCD camera In addition to a CCD camera, another device operating in an analog manner can also be used, provided that it is suitable for meeting the stated purpose. However, these other facilities are generally more complex than the one mentioned.
- the motor 44 can also be indirectly attached to the holder 45.
- Another more practical and inexpensive option is to install a camera 40 that is capable of providing an ultimately visible image. The electrical ones correspond to the image observed by the camera
- the picture itself corresponds to that according to Fig. 2.
- the control buttons 42 and 43 are assigned to the screen 41, the actuation of which, for example, enables the motor 44 to be rotated in one or its other direction of rotation.
- the motor 44 is fastened to the holder 45 of the respective upper knife 10 and can rotate a gear 46.
- the gearwheel 46 engages in a toothed rack 47 or a similar device which is fastened to the housing of the machine device parallel to the geometrical axis of the lower knife 6, for example to the machine frame 14.
- an operator can, for example at the control panel of the machine or from another suitable location, observe the position of the upper knife 10 to be observed with respect to its respective position relative to the lower knife 6 and, if necessary, correct it by hand at the push of a button.
- the camera used for this is, for example, a Micam camera from Digital Vision Technologies, 29 AV Champollion, F-31100doch.
- suitable lenses for this camera it is possible to vary the image section captured by the camera, for example to design it in such a way that the effective position of at least one upper knife 10 and at least two cutting edges of the lower knife 6 is detected.
- a particularly well visible image results when a light source 48 is positioned on the side of the upper knife 10 opposite the camera 40, in other words the camera 40 is forced to work in the backlight.
- the lower knife 10 and its holder 45 can also be fastened to the slide 16 and displaceable relative to it within certain limits.
- the movement of the camera and slide takes place essentially and preferably in the direction of the geometric axes of the lower and upper knife or at least parallel to these.
